SwitchGlo Pro Version 6 Firmware updates include:

1. Increased glow intensity.

2. Increased 12 second auto shut off to 15 seconds.

3. Changed Sip-1 UP; 60 second auto shutoff changes to always "ON", meaning no auto shutoff while switched ON.

4. Added "Pushbutton extended glow termination". For Pushbutton users who press the button multiple times for extended glow, they can now hold the button down for 2 seconds to kill the glow early.

5. Added LED pin-outs on SwitchGlo Pro's "Pushbutton Port", now called "Accessory Port". For use with LED extensions accessories (sold separately) which allow you to see the LED light up when your SwitchGlo Pro is activated and your glow plug is glowing.

6. Added 15 sec glow buzzer during Sip-1 UP (glow always ON) & Sip-4 UP (Buzzer OFF) scenario. For users running full time glow and don't want to hear the buzzer, this allows for the buzzer to activate for only the first 15 seconds of glow giving the user a buzz during engine start. This also allows the craft locator feature to stay in tact.
